Why not use jzmq?

I agree, look at finding the bottleneck as I don't think inproc will be faster than JNI

Interesting. We are generating bindings for CZMQ using zproject, don't have a JNI generator yet. ... :)

You could use inproc yes, except you still need to call the libzmq API to send/receive messages. It's probably better to look at finding the bottleneck.
